Description copied from class: DataSetDescriptor

getDataSetImpl implements the getDataSet for this DataSetDescriptor implementation. The getDataSet call of the abstract DataSetDescriptor uses this routine to satisfy requests and fill its cache. This caching may be disabled via setDefaultCaching. To satisfy the request, a DataSet should be returned with an x tag range that contains start and end, with a resolution finer than that requested.

Specified by:

getDataSetImpl in class DataSetDescriptor

Parameters:

start - beginning of range for the request.

end - end of the range for the request.

resolution - the resolution requirement for the reqeust. null may be used to request the finest resolution available or intrinic resolution.

Throws:

DasException

getXUnits

public Units getXUnits()

Specified by:

getXUnits in class DataSetDescriptor

Returns:

the x units of the DataSetDescriptor that parameterize the data. This is used to identify dataSet requests.

main

public static void main(java.lang.String[] args)
